#1

Just in the past couple days, FirefoxNightly won’t launch for me. I see the beginning of an outline of a window pop up, and then it just segfaults. Anyone else having issues with it? If I run it from command line I get:

F: Running 'bwrap --args 37 firefox'
Attempting load of libEGL.so
Exiting due to channel error.
/app/bin/firefox: line 8:     3 Segmentation fault      (core dumped) firefox-bin $*

Doesn’t matter if I try safemode or anything else. I tried a brand new user on my system well to see if maybe it was my settings/extensions, but got the same behavior. This is the version I’m running:

  1. The Firefox Nightly flatpak was (finally) recently updated
  2. I’m also having a problem running the Firefox Nightly flatpak on Silverblue (but it’s “due to a channel error” related to “ipc_channel_posix”)
  3. The official Firefox Nightly from Mozilla’s upstream tarball runs on Silverblue 31 here
  4. The Firefox Nightly flatpak doesn’t work on non-Silverblue Fedora 31 either (where I am seeing the libEGL message and then also the connection reset by peer “ipc_channel_posix” issue too).

So… this seems like an issue specific to the Firefox Nightly Flatpak.

Here’s my error log when running flatpak run org.mozilla.FirefoxNightly:

Unsurprisingly, flatpak remote-info shows the same exact output on my system.

Well, this is where the power of flatpaks come in right? We can easly revert to the previous commit and run that one. Am I doing this right?

Encountering the same problem after Nightly got updated:

[:package: com.gexperts.Tilix ~]$ flatpak run org.mozilla.FirefoxNightly

(firefox:3): Gdk-CRITICAL *: 11:21:42.036: gdk_screen_get_monitor_scale_factor: assertion ‘GDK_IS_SCREEN (screen)’ failed
[Socket 20, Chrome_ChildThread] WARNING: pipe error (3): Connection reset by peer: file /run/build/firefox/ipc/chromium/src/chrome/common/ipc_channel_posix.cc, line 358
/app/bin/firefox: line 8: 3 Segmentation fault (core dumped) firefox-bin $

So I upgraded to FSB31 but that didn’t fix the issue. Also unable to execute the workaround suggested by @britthouser since the command doesn’s seem to work: :

[📦 com.gexperts.Tilix ~]$ flatpak remote-info --log Firefox org.mozilla.FirefoxNightly
error: Remote "Firefox" not found

With my source being:

[📦 com.gexperts.Tilix ~]$ flatpak remote-list
Name                    Options
fedora                  system,oci

Firefox Developer Edition          org.mozilla.FirefoxDevEdition                           master
Firefox Nightly                    org.mozilla.FirefoxNightly                              master

What would be the right command to downgrade Nightly?
